## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability tariffmonkee-email-verify-e925f9a7
```

Example prompt: Can you check whether john.doe@example.com is a real, deliverable email address — specifically if it has MX records, passes syntax checks, isn't from a disposable/temp-mail domain, and has SPF/DMARC set up?

## When to prefer this

Choose this endpoint when you need a fast, single-address deliverability check that covers syntax, DNS (MX, SPF, DMARC), and disposable domain detection without performing a full SMTP handshake. Ideal for agent workflows that need to screen user-submitted emails before sending, onboarding, or storing them. Prefer it over full domain audit tools when the scope is strictly one email address and speed matters.

## Known failure modes

- Malformed or missing email address input returns an error
- DNS timeout or lookup failure may result in inconclusive MX/SPF/DMARC checks
- Newly created disposable domains not yet in blocklists may pass the disposable check
- No guarantee of mailbox-level existence (SMTP probe not performed)
- Rate limiting or payment failure returns 402 or 429 status

## How this service works

Email address -> deliverability verdict. Checks syntax, MX record presence, disposable/temp-mail domain match, and SPF/DMARC presence on the domain. Scoped to a single address, not a full domain security audit.

## Output

Returns a deliverability verdict for the single email address, including: syntax validity, MX record presence on the domain, whether the domain is a known disposable/temp-mail provider, and whether SPF and DMARC DNS records are present on the sending domain.
